Frequently Asked Questions
If your business is GST-registered, you must itemize GST as a separate line on every invoice—it's a legal requirement. Show the net amount, GST amount at the applicable rate (typically 10%), and the total including GST. If you're not GST-registered, clearly state "GST not applicable" or omit it entirely. This clarity protects both you and your client, and ensures your tax records align with the ATO's expectations when you lodge your activity statement.
Your Australian Business Number (ABN) is essential if you're GST-registered—clients expect to see it. Include your legal business name, physical address, and contact details. On the client's side, show their name and address clearly. Each invoice needs a unique invoice number, issue date, and payment due date in Australian date format (DD/MM/YYYY). These details ensure compliance with ATO record-keeping standards and help establish legitimacy and accountability when clients verify business credentials.
Monthly invoicing suits predictable, recurring work where you're providing continuous services—think retainer arrangements, maintenance contracts, or subscription-based offerings. Per-project invoicing works better when deliverables are discrete and completion-focused. Monthly cycles create payment predictability, improve cash flow forecasting, and simplify accounting for both you and your client. However, if your work is genuinely project-based, monthly billing can frustrate clients because it doesn't reflect natural work boundaries, potentially causing payment delays or disputes.
Monthly invoices create a regular paper trail that satisfies ATO audit requirements—you have a documented invoice for every transaction, issued in sequence. The ATO expects invoices to be issued by the time you supply goods or services, though for ongoing monthly services, invoicing at month-end is standard practice. Keep digital copies with dates, amounts, and GST details. This regular invoicing rhythm actually simplifies tax time because your records are naturally organized chronologically, reducing reconciliation work during activity statement preparation.
Common Australian terms range from payment upon receipt to 14–30 days, depending on your relationship and industry. Freelancers and smaller businesses often use shorter terms (7–14 days) to preserve cash flow, while established B2B relationships may accept 30 days. State your terms clearly, including your preferred payment method—bank transfer via BSB and account number is standard in Australia. Be specific: "Payment due by [date]" works better than vague language. Balance your cash flow needs against market norms to maintain client relationships.
Invoicing interstate clients uses the same GST and ABN rules as invoicing within your state—there's no distinction for tax purposes. Include your physical business address and the client's address, regardless of state. If you're providing services across borders, GST still applies if you're registered. The main consideration is payment logistics: most Australian businesses use bank transfers, which work seamlessly across states. State differences don't change invoicing requirements, but including both addresses helps with dispute resolution if you need to reference the service jurisdiction.
If you're invoicing export sales (goods physically leaving Australia), GST doesn't apply—these are GST-free under Australian tax law. Your monthly invoice should clearly show "GST-free export" rather than listing a GST amount, proving to the ATO that you've correctly claimed the exemption. However, the goods must genuinely leave Australia; if they stay domestically, GST applies regardless. For export invoices, consider adding shipping or port details to demonstrate the export context, which strengthens your tax position with the ATO.
Don't alter the original invoice—this creates audit trail problems and looks unprofessional. Instead, issue a credit note for the incorrect amount and then re-invoice with correct details, or issue a single corrective invoice clearly marked "Amended Invoice" with a reference to the original number and date. This keeps your records clean and demonstrable to the ATO. If the error involves GST, the correction method matters even more because it ensures your GST reporting remains accurate and defensible during audits.
